The high precision CNC quad bearing live center is especially useful for grinders, CNC turning centers and manual lathes. The extended point of the live center has been optimized for high rigidity and outstanding tool clearance, the company says. It has a runout guaranteed to ± 0.00005” TIR or better.

Bearing life is said to be significantly extended with the Roto-Shield coolant slinger and upgraded, long-life, spring-loaded seal that is resistant to abrasion, high temperatures and virtually all metalworking fluids.

This live center model incorporates three precision angular-contact bearings that are secured to the point with a locknut to form a rigid preloaded assembly. This design is similar to a machine tool spindle cartridge and is made to provide outstanding accuracy and rigidity.
 
The point of the Royal High Precision CNC Quad Bearing Live Center extends into the center’s body where it is supported by a needle roller bearing. This further increases rigidity, reduces point deflection and dampens vibration. The low-profile head of the live center offers exceptional tool clearance, the company says.
